Ordering of items in dropdown menu?

Hello everyone,

I am using Deliver theme in my GRAV website. I was asked to arrange the items in the dropdown navigations alphabetically.

I am aware of the possibility of different ways of ordering the pages (collections), which I use in sidebar.html.twig. So far I have not found a way of influencing the order of items in the dropdowns, though. The file navigation.html.twig does not seem to be the place to put some ordering logic in.

Will you point me in the right direction, please?

Why have you decided this? This is exactly where I would do it.
